I have a 2005 Freightliner Columbia. On the starter selnoid on the firewall, one of the small wires at the plug is hot all the time?? Should this only be hot when the key switch is ingaged?? Would anyone have a wiring diagram for the starting system on this truck??
My problem is that one of the little wires to the solenoid is always hot, I do not beleive it should always be hot, only when the key swith is initaited. One is a ground and one is hot, but should not be hot all the time. So something in the dash, a relay or something is wrong for the wire to be continously hot??
